How can the utf8_decode() function be used to address encoding problems with special characters in PHP applications?

Special characters in PHP applications can sometimes cause encoding issues, especially when dealing with UTF-8 encoding. The utf8_decode() function can be used to convert UTF-8 encoded strings to ISO-8859-1, which can help address problems with special characters. By using utf8_decode(), you can ensure that special characters are displayed correctly in your PHP application. 

// Example of using utf8_decode() to address encoding issues with special characters
$utf8_string = "Café"; // UTF-8 encoded string with special character
$iso_string = utf8_decode($utf8_string); // Convert UTF-8 to ISO-8859-1

echo $iso_string; // Output: Café (special character displayed correctly)
